bubbles form
brown-red powder is formed
Magnesium Oxide Reacts With Sulfur Trioxide added: Magnesium sulfate is formed: MgO + SO3 --> MgSO4
magnesium sulfate
When magnesium reacts with copper chloride, an exchange reaction occurs in which magnesium replaces copper, resulting in the formation of magnesium chloride and copper. The balanced chemical equation for this reaction is: Mg + CuCl2 → MgCl2 + Cu.
When dilute sulfuric acid reacts with copper(II) carbonate, blue copper(II) sulfate solution is produced.
The zinc is either contaminated with copper, or the copper is depositing so quickly onto the zinc that it is in a non crystalline structure and therefore appears to be black. Try melting some of the black stuff with a blowtorch and see what happens.

magnesium sulfate
Magnesium sulfate is obtained.
the copper sulfate reacts and changes colour
magnesium
I don't know! That's what we're trying to figure out!! Oh MY GOSH!!
Copper sulfate is dissociated in water.
When magnesium reacts with copper chloride, an exchange reaction occurs in which magnesium replaces copper, resulting in the formation of magnesium chloride and copper. The balanced chemical equation for this reaction is: Mg + CuCl2 → MgCl2 + Cu.
Since magnesium is a more reactive metal, it will displace the copper and the anion (Which basically is the sulphate) goes to the magnesium. So the products you get out of the displacement is Magnesium sulphate, and copper alone. I have tried this experiment before and just to tell you one thing... During the reaction, a smell comes up, so cover your nose! :D You don't want to smell it.
Single-Replacment
Copper sulfate dissolves in water, it does not react.
When dilute sulfuric acid reacts with copper(II) carbonate, blue copper(II) sulfate solution is produced.
